OlL ER FOR CAR-JOURNALS.

SPECIFICATION forming part of Letters Patent No. 714,272, dated November25, 1902.

Application filed February 15, 1902. Serial No. 94,191. (No model.)

To all whom it may concern.- Be it known that I, ERNEST ARMSTRONG, acitizen of the United States, residing at Camden, county of Camden, andState of New Jersey, have invented a new and useful Improvementin Oilersfor Gar-Journals,of which the following is a full, clear, and exactdescription, reference being bad to the accompanying drawings, whichform a part of this specification.

My invention relates to oilers for car-journals. It has for its objectto improve oilers of this character, andparticularly of the type shownin Letters Patent No. 663,407, issued to me December 11, 1900. A seriousimperfection in oilers of this class is the tendency of the surface ofthe pad in contact with the journal to become glazed -that is, to getsmoothby reason of its being held under spring-pressure in contact withthe rapidlyrevolvingjournal. For the same reason there is a tendency ofthe pad to be compressed, and thus rendered relatively non porous. Thiscondition of the bearing-surface and interior of the pad elfects itscapacity to take up oil and to feed it to the journal. It is also notaltogether desirable to construct the supporting-springs in the mannershown in said patent, as it does not secure the desired delicacy ofspring-pressure, resulting in a tendency to. compress the pad by virtueof too strong pressure-against the journal and making it less convenientto depress the device for the purpose of introducing-and removing thepads.

The object of my invention is to remedy these imperfections.

It consists of novel means for preventing the glazing of the pad and ofan improved construction of supporting-spring.

Inthe drawings, Figure 1 is a longitudinal vertical section of acar-axle box, showingthe car-axle within the box and the lubricatingdevice inoperative position therein.

is a transverse section on the line 2. 2 of Fig. 1. Fig. 3 is aperspective View of the lubricating device,part of the side pads andfeeders being omitted for purposes of illustration. Fig. 4 is asectional view of one of the spacers. Fig. 5 is a perspective Viewshowing a spacer Fig. 2

in position on the lubricating device. Fig. 6 is a diagrammaticviewshowing the formation of the bottom and body of the pad and thefeeders.

A is the axle.

B is the journal, turning in bearings in the journal-box 0.

1 designates a plurality of curved springsupports, having a horizontalplate 2 connected therewith at the center of length,there being aplurality of inversely-curved arms or pad-holders 3 secured upon theplate 2 and to the curved spring-supports l by means of rivets or screws4. The curved arms 3 have a semicircular contour coincidingsubstantially or approximately with the periphery of the journal B. Theparts 1, 2, and 3 form the base for supporting the pad D, to whichthrough the wicking or feeders 6 the oil is conveyed and which bycontact with the journal maintains it lubricated.

In order to increase the resiliency of the spring-supports,l form themas follows: Each support is curved upwardly and inwardly from its lowerend, thence abruptly outwardly and in a gradual curve upwardly andinwardly, the top thereof or that part to which the plate 2 is securedbeing substantially fiat. This greatly increases the resiliency of thespring over the semi-elliptical form shown in my said patent and causesthe pad to press against the journal with a more delicate and yet quitesufficient pressure. At the same time it increases the compressibilityin a vertical direction of the base, thus facilitating its insertiOnwithin the box.

The pad D is formed in three sections, the central section 5 restingimmediately upon and over the plate 2 and the side sections 7 7 restingupon the ends of the curved arms 3. Extending beyond each edge of eachsection and secured thereto or integral therewith are feeders 6. The padmay be formed of any desired porous material capable of holding insuspension a large quantity of oil, and the feeders may consist of anymaterial capable of conveying the oil by capillary attraction to thepad. Preferably, however, the feeders consist of a large number of thicklooselytwisted cotton or other wick threads, and

each pad-section is formed by interweaving these wickthreads togetherthroughout a portion of their length to form the base of the pad and byprojecting a number of the wick-threads above the interwoven surface ofthe pad-section and cutting them off, so that each pad-section consistsof a more or less closely-woven base and a body composed of a largenumber of closely-associated upwardly projecting wick threads,- whilethe feeders are integral with the pad -section. By making the pad insections, which of course may or may not be separate from each other, Iam enabled to provide so large a mass of wicking that it is possible tofeed to the journal a quantity of oil sufficient to thoroughly lubricateit when turning at its highest speed. The outer set of feeders of theside pad-sections are somewhat longer than the other feeders, so thatall the feeders will project to an equal extent into the reservoir ofoil at the bottom of the box. The side sections 7 7 are secured to thearms 3, while the central section 5 is secured, preferably, to the plate2 between the arms 3. I have provided the following means for securingthe pad to the base and at the same time prevent glazing of the pad.

8 8 are spacers having a central orifice 9 of relatively large diameterat the top and a central orifice 10 of relatively small diameter at thebottom, an annular shoulderbeing formed where the two orifices meet inthe interior of the spacer. These spacers, which are of less thicknessthan the body of the pad, are placed on the uppersurface of the pad, andby means of suitable rivets 11, inserted into the orifices 9 andextending through the orifices 10 and the arms 3 or plate 2, the pad issecured to the base and the spacers sunk into the bottom of the pad. Atthe same time these spacers by contacting with the journal prevent thepad from being pressed as closely as it otherwise would be against thejournal. This prevents the pad from being packed or compressed and itssurface from becoming glazed, and thus maintains its porosity and itscapacity to feed the necessary quantity of oil to the journal.

Having now fully described my invention, what I claim, and desire toprotect by Letters Patent, is v 1. An oiler for journals comprising abase, a thick capillary pad resting thereon and capillary feedersextending from said pad and adapted to connect the pad with theoil-supply and spacers sunk into the body of the pad of a thickness lessthan the thickness of the body of the pad, thereby permitting the pad tocontact with the journal but restricting the pressure of the sameagainst the journal and thus preventing glazing and maintaining thecapillarity of the pad.

2. An oiler for journals comprising a base, a pad resting thereon, andcapillary feeders extending from said pad and adapted to connect the padwith the oil-supply, the pad consisting of a woven bottom and a body ofclosely-associated capillary threads extending upward from the bottom,and spacers secured upon the woven bottom and of less thickness than thelength of the upwardlyextending threads.

3. An oiler for journals comprising a base, a capillary pad restingthereon, and capillary feeders extending from said pad and adapted toconnect the pad with the oil-supply, spacers sunk into, and of lessthickness than, the body of the pad, and securing means engaging thespacers and the base, thereby securing the pad to the base andpreventing glazing of the pad.

at. An oiler for journals comprising a base, a capillary pad restingthereon, and capillary feeders extending from said pad and adapted toconnect the pad with the oil-supply, spacers sunk into, and of lessthickness than, the body of the pad, the spacers having hollow interior,and securing means extending from the hollowinterior of the spacerthrough the pad and engaging the base.

5. An oiler for journals comprising a base and an oiling-pad thereon,the base consisting of supporting-springs, plates thereon, and holdersabove the plates for holding the pad, the supporting-springs beingcurved inwardly and upwardly from their lower ends, thence outwardly,upwardly, and inwardly, the top thereof being flat, and the plates beinglocated over the flat top, and means for securing the parts of the basetogether.

In testimony of which invention I have hereunto set my hand, atPhiladelphia, on this 7th day of February, 1902.

ERNEST ARMSTRONG.
